Call Home

The Call Home feature allows to initiate a secure connection with configured remote management systems for additional configuration or register the presence of the system.

Overview

Call Home supports both the initial deployment of vCPE and on-going management. During the Zero Touch procedure on vCPE, the configuration is automatically fetched and may contain the Call Home server address and the set service netconf command. The system automatically initiates a secure connection with an NMS and is ready to be further provisioned and managed by that NMS.

Limitations

The Ciena implementation of Call Home has specific limitations as discussed in this section.

The following list describes those limitations:
  • The Call Home specification in the IETF draft supports both SSH and TLS transports. Currently, Ciena supports the SSH transport only. The SSH protocol is defined in the IETF draft The Secure Shell (SSH) Transport Layer Protocol, available at https://tools.ietf.org/html/rfc4253.
  • The Call Home specification in the IETF draft supports both NETCONF and RESTCONF as configuration servers. Currently, vRouters support NETCONF configuration servers only. The NETCONF support for SSH is defined in the IETF draft Using the NETCONF Protocol over Secure Shell (SSH), available at https://tools.ietf.org/html/rfc6242.

For more information about Call Home, refer to the IETF draft NETCONF Call Home and RESTCONF Call Home, available at https://tools.ietf.org/html/draft-ietf-netconf-call-home-08.

Configuration sample

In a scenario where the Zero Touch procedure does not push the Call Home server address to the system, you can use the service netconf call-home netconf-client <host> port <port> command to initiate the Call Home service.

Assume that a vCPE guest is connected to a NMS server. The NMS server has an IP address of 10.0.0.1.

To configure Call Home, perform the following steps.

Table 1. Configuring Call Home
Step Command
Log in to vCPE and switch to configuration mode.
vyatta@vyatta# config
Initiate the Call Home service.
vyatta@vyatta# set service netconf call-home netconf-client 10.0.0.1 port 443
Save the configuration.
vyatta@vyatta# commit
Switch to operational mode.
vyatta@vyatta# exit
logout
Display the result.
vyatta@vyatta:~$ show service netconf call-home status

If you want to disable Call Home, you can use the service netconf call-home netconf-client <host> disable command.
